CAR-DOOR.

Application filed September 6, 1911.

To all whom it may concern:

Be it known that we, WVILLIAM H. HoL- LAND and FRANK J. KALTENBAOI-I,citizens of the United States, residing at Edgewood and Echo Point,respectively, in the county of Ohio and State of Vest Virginia, haveinvented certain new and useful Improvements in Car-Doors, of which thefollowing is a specification.

Our invention relates to doors for railway cars, and the primary objectof the invention is the provision of a car door of a very simple andeffective construction which may be securely held in its closed positionand which is easily opened upon unlocking.

Another object of the invention is to provide a car door which insteadof sliding, as do ordinary car doors, is pivotally mounted at one cornerso that it may be shifted rotatably on its pivot in a plane parallel tothe side of the car instead of being slid to its opened or closedposition.

Another object is to so mount a door of this construction that thejunction of the door with the abutment against which the door seats whenin its closed position will be protected, thus preventing the insertionof instruments whereby the door may be disengaged from the lockingmeans.

A further object is to provide means in connection with said doorwhereby the door when it is turned to its closed position may be forcedagainst the side of the car so as to hold it in tight engagement withthe side of the car and seal the door opening.

Minor objects will appear in the course of the following description.

Our invention is illustrated in the accompanying drawings wherein:

Figure 1 is a side elevation of a portion of a car with the door thereofclosed. Fig. 2 is a like view to Fig. 1 but showing the door in itsopened position. Fig. 8 is an enlarged horizontal section on the line3--8 of Fig. 1. Fig. 4 is an enlarged vertical section on the line 41 ofFig. 1. Fig. 5 is an enlarged face view of the locking mechanism. Fig. 6is a fragmentary perspective View of a portion of the door and the wallof a car, the door being shown in the position it will take as it movesupward to its closed position.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingsby the same reference characters.

Specification of Letters Patent.

Serial No. 647,931.

Referring to these drawings, 2 designates a freight car of any ordinaryconstruction and. 3 designates the door opening thereof.

4 designates the door which is larger in area than the door opening and5 designates the abutment which extends vertically at one side of thedoor opening against which one edge of the door bears when the door isin its closed position. The door is pivotally mounted at the uppercorner away from the abutment 5 by means of the pivot bolt 6 whichpasses through the door, passes through the side of the car and isprovided on its inside face with the lock nuts 7. WVear plates 8 ofmetal are disposed upon the contacting faces of the door and side of thecar, and a wear plate 9 is also disposed upon the outer face of theupper corner of the door.

The angular brace 10 is attached on the inside face of the side of thecar, extends over the upper edge of the car side and then downward tothe front face of the upper corner of the door. Disposed between thedownwardly extending end of the brace 10 is the guide strip 11. The bolt6 passes through the brace 10, the guide strip 11 and through the doorand the side of the car. The opening for the passage of the bolt 6through both the door and the side of the car is preferably reinforcedby a liner or wear tube 12. The guide strip 11 extends horizontallyalong the car in front of the door opening and is attached at its otherend in any suitable manner to the upper end of the abutment 5. Thisguide strip 11 acts to hold the upper edge of the door in close contactwith the side of the car when the door is in its closed position.

The edge of the door opposite to its pivotal point and at the lowercorner is formed with a bolt opening 13 and the lower end of theabutment 5 is recessed as at 14: for the reception of any desiredlocking mechanism adapted to engage with the bolt opening 13. As shown,the locking mechanism comprises a plate 15 carrying the longitudinallyshiftable bolt 16 which is supported in guiding eyes 17 and is forced toits projected position by means of a spring 18. Mounted upon a pivotbolt is a rotatable member 19 having the radial outwardly directed arm20 connected by a link or other suitable connection to the outerextremity of the bolt 16. Then the rotatable member 19 is turned in onedirection, the bolt 16 will be withdrawn against the force of the spring18 and the bolt will be withdrawn from engagement with the bolt opening13 of the door. When released, however, the spring 18 will act to throwthe bolt into engagement with the door. The rotatable member ispreferably formed with a many sided shankwhich may be engaged by a keyformed to fit the shank.

It will be obvious that the shank of the member 19 may be varied in formso that only a certain key will unlock the car door. As shown, thisshank is square and the key 19 is shown as formed with a square socketto fit the square shank. The key opening is protected by means of anescutcheon 22 upon the exterior face of the door, this escutcheon havinga central opening through which the key may be inserted.

For the purpose of forcing the door toward the side of the car andholding it in such position, we provide the lower corner of the car dooropposite to the bolt opening 13 with a perforation 23 through whichpasses a screw 2 1. This screw does not engage with the wall of theperforation 23 but engages with a screw threaded liner tube 25 whichextends through the wall of the car. The head of the screw is formedwith a collar 26, which when the screw is screwed home engages the wearplate 27 on the face of the door and forces the door inward. The head ofthe screw is also connected to a chain 28 whereby the screw may beconnected to the car. Preferably the screw is provided with a crank atits outer end, designated 29, which crank is perforated for engagementwith a hooked wire or othersuitable fastening device attached to the cardoor itself. After the screw is screwed home, this hook, wire or otherdevice 30 may be engaged wit-h the crank through the perforation 31therein and a seal applied, thereby preventing the removal of the screw24 unless the seal is broken and thereby preventing an opening of thedoor withoutbreaking the seal.

In order to support the door in its opened position we preferablyprovide a spring latch 32 which is mounted upon a pivot bolt 33 aroundwhich is wound a spring 341 having an offset extremity which engages thelatch and holds it in its upwardly extending position. The latch isformed with a handle 35 whereby it may be readily actuated. \Vhen thedoor is swung to its opened position, the corner of the door will slippast the latch 32, turning the latch against the force of the spring.When the door has passed the latch, the latch will spring to theposition illustrated in Fig. 2 and hold the door supported. "We do notwish to limit ourselves to this particular means of holding the doorsupported.

The car and door are constructed as ordinarily but preferably the dooris formed of two thicknesses of material, the boards of the outsidethickness extending vertically or in one direct-ion, while the boards ofthe inside thickness extend at an angle to the boards of the outsidethickness, thus preventing the door from warping.

In order to prevent the insertion of an instrument between the abutment5 and the adjacent edge of the door when the door is closed, we attachto the face of the abutment 5 the protecting plate 36 which is of sheetmetal and extends the whole length of the abutment and projectsinwardlybeyond the inner edge of the abutment. The inner margin of this sheetmetal plate is slightly curved outward so as to form a guide permittingthe door to be readily swung into position. When the door is swung intoposition and locked,the edge of the door and the adjacent edge of theabutment will be protected by the plate 5.

It will be seen that our device is simple in construction, easilyapplied to doors and that the door swings open very readily'when onceunlocked. Sliding car doors are very apt to stick and it is verydiflicult to push them open. The necessity of providing some meanspermitting the door to move outward in order to permit it to slidereadily and forcing it inward when in its closed position also tends tocomplicate sliding door constructions. Our device is particularly simpleand when unlocked and the screw 24 removed, the door swings downward andmay be readily turned to its opened position.

l/Vhat we claim is: p

A car having a door opening, a vertically disposed abutment extendingparallel to one margin of the door opening, an angular supporting memberattached to the inside of the car, projecting out from the car and thendownward, a door disposed between the outwardly and downwardly extendingend of the supporting member in position.

to close said opening, a pivot bolt passing through said member, throughthe door and through the car forming a pivot for the door, and a guidemounted at one end upon said pivot bolt and extending parallel to theupper margin of the door opening andattached at its other end to saidabutment.

In testimony whereof we affix our signatures in presence'of twowitnesses.
